Doesn't make sense

I bought a coffee machine while they had a promotion on coffee pods. The machine was delivered but the pods were not included. When I contacted them to find out about the pods, they said I had to return the machine. I also had to send photos of the bar code and of the machine. The problem was not with the machine. The problem was that they did not include the pods as they promoted on their website. I don't understand their logic. They had my order details, I sent the photo's as per their instruction. Why would they need the machine back?! I have to wait a week for them to go through their evaluation process. Inconveniencing me because they slipped up on an order. This was my first order on takealot, but I learn from my mistakes. . . never again.
